It was as if the whole world had been cut off from him, and all of Bird's senses had retreated underwater, and he could feel the bursts of energy Bird that Elro's spell had struck on the water curtain, but it was often a burst of light that he could only feel for tens of seconds after a burst of light.

At this time, Bird was a little weird, and something similar to a fish gills actually grew on his cheeks, and it continued to open and close slightly, as if he was breathing the air in the water, this is the fish gills potion, which was prepared by Bird when he was idle in the two-story building in Anxi Town, but I didn't expect it to be really useful today.

After a moment of acclimatization to the underwater world, Bird began to swim towards the sinking point in the puddle. He had already determined his orientation long before he got into the water, and now he could feel the direction of the river in the puddle, and Bird swam a little forward, and then his whole body began to shake, and his whole body was carried up by the flowing water, and he leaned towards the center without the slightest effort.

When Bird was swept into the center of the whirlpool, he could no longer control his body, and he was suddenly swept into the whirlpool.

"Poof" Bird felt himself fall into the water again, and it took him a moment to recover from his dizziness, and coming in from the whirlpool was simply his own abuse, and Bird almost threw up the dinner he had eaten during the college break for lunch.

The good thing was that the whirlpool was not very long, and it fell into the calm water again, allowing Bird to slow down and recover for a long time.

When Bird opened his eyes, he was a little frightened by what he didn't see.

It was as if he had fallen into a huge cavern, surrounded by countless extremely hideous murals, and Bird was extremely close to one of them. In addition, the cave was brightly lit, as if it was daytime, and it was already dark outside.

And the strange sight in the cave at present also surprised Bird. The cavern resembled a large cistern, and there was a passage directly above the cavern, where Bird entered. A huge whirlpool was formed in the passage, and the water in the cave was constantly being sucked up, like a huge column of water flowing out of the passage, but after a while it would stop again, and then the water poured in from the outside, forming another column of water.

Bird suddenly understood that the purpose of the circle was to suck the water out of the cave.

Bird then drilled down, trying to know how deep the water was, or how big the cavern was. But the water was not as bright as day as it was, but an endless black, and Bird dived some distance, but he could not see the bottom of the cavern, and the distance under the water was extremely short.

It seems that the water sucked out by the formation is only a small half of this cave, and if the water in this entire cave is sucked dry, I don't know how long it will take, and I don't know what scale of flood will occur.

Bird didn't dive any further, but wanted to find the core of the formation. Bird tricked himself into a flying spell and floated himself directly into the cavern.

Bird slowly raised his distance, trying to get closer to the passage of water, to observe the core of the water-absorbing formation. Bird then looked down at his feet, and then realized the size of the cave, and the water in the whole cave was like a black mirror, and like a pool of stagnant water.

Bird vaguely felt that there was something underwater, but he couldn't see it clearly, and he didn't dare to take a closer look at it at this time, he just wanted to quickly find the core of the formation, destroy the formation, and then escape from the cave.

Flying in the middle of this cave, you can observe not only the size of the cave and the surface of the lake, but also the murals that cover the entire cave.

After years of immersion in this cave, the mural has not faded or been soaked and peeled off, and it seems that the color of this mural is only slightly dull and not so hideous. But in Bird's opinion, this is already hideous enough.

The mural was full of bloody scenes of corpses. Looking around the entire visible area, it seems to be telling a whole story, but Bird can't see the cave far away, so he doesn't know what the entire mural is about.

At this moment, there were ripples in the black water of the cavern, and Bird was sure that he had indeed seen a black shadow, which was swimming slowly under the water of the lake, and Bird quickly continued to fly upwards to keep himself away from the black lake.

Bird soon touched the top of the cavern.

It's still a little wet, and it seems that the entire cave should have been this black lake before, but after being sucked out of part by the water absorption array, this piece was left empty. The top of the cave was still painted with murals, but it was not like the style that Bird had seen before, but now Bird couldn't see the panorama, so he just looked at it slightly, and then began to grope for the core of the formation towards the water entrance and exit.

Some slippery things that Bird touched, black-green, looked like they should be water stains, which was extremely disgusting, especially when Bird hadn't found the clue of the formation now, Bird was even more anxious, because he hadn't even touched the trace of the formation, and the traces of the use of mana had never been found.

Bird looked around the entire cave, the black shadow under the lake had disappeared at this time, Bird remembered whether this formation would be under the surface of this lake, impossible, under the surface of the lake, there were no fingers at all, and it was extremely deep, how could the formation be arranged under this.

"Could it be this light?" a thought suddenly flashed through Bird's mind, and he immediately set off and flew towards the light source in the cavern.

Sure enough, this light source was part of the formation, and Bird saw a blue-white stone block embedded in the top of the cave, and a trace of blue smoke could be seen in the stone, swinging randomly in the stone.

'It seems to be a Hailan stone,' Bird reached for it, trying to remove it.

Suddenly, a black shadow came out of the gap behind the stone and rushed straight into Bird's face, the magic power in Bird's body suddenly stopped, and the flying technique that was originally blessed on his body was suddenly gone, and he saw Bird falling straight down. And the black shadow actually pounced into the air and fell directly into the water. Bird actually dodged the attack of this thing.

Bird had just breathed a sigh of relief and blessed himself with flying skills again to keep himself from falling into the water of the lake, when he suddenly noticed a huge black shadow appearing under the lake.
